Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and frac ....Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.Read moreRead less

This project aims to create a breakthrough switching dynamics approach and new technology to speed up finding optimal solutions. It will develop a distributed switching dynamics based optimisation scheme for global optimisation problems in industrial big-data environments where timely decision making is required. It will result in a practical technology for industry optimisation problems such as economic energy dispatch in smart grids and optimal charging and discharging tasks in a large network of electric vehicles, helping Australian power industry improve efficiency and security, as well as training the next generation scientists and engineers for Australia in this emerging field.Read moreRead less
Olympic Dam in a Test Tube: Critical Experiments and Theory for Understanding Fe-Cu-U-REE in Hydrothermal Fluids and during Fluid-Rock Interaction. Olympic Dam (OD) is a supergiant Cu-U-Au-Ag-REE ore deposit, containing more than a trillion Australian dollars worth of metals, and hosted by hematite-rich breccia in South Australia. Yet, key aspects of the geochemistry of OD-style deposits remain poorly understood. This project will conduct innovative experiments to address the role for fluorine i ....Olympic Dam in a Test Tube: Critical Experiments and Theory for Understanding Fe-Cu-U-REE in Hydrothermal Fluids and during Fluid-Rock Interaction. Olympic Dam (OD) is a supergiant Cu-U-Au-Ag-REE ore deposit, containing more than a trillion Australian dollars worth of metals, and hosted by hematite-rich breccia in South Australia. Yet, key aspects of the geochemistry of OD-style deposits remain poorly understood. This project will conduct innovative experiments to address the role for fluorine in Fe, U and REE transport at OD, and the role of fluid-rock interaction in generating the unusually oxidised Fe-Cu mineral assemblages and in controlling U grades and distribution. The fundamental information gained will underpin intense on-going research aimed at discovering new OD-style orebodies and at creating new ore-processing technology that are environmentally sustainable and able to access lower-grade ores.Read moreRead less
Improved image analysis: maximised statistical use of geometry/shape constraints. This project will improve image analysis to apply such applications as 3D street-scape reconstruction, synthetic inserts into video for special effects, autonomous navigation, and scene understanding. It will do so by maximally exploiting the geometry of planar surfaces (e.g. walls) and straight lines and other simple geometric shapes.
